GALVANIC PATENT OFF CE.

SPECIFICATION forming part of Letters Patent No. 275,797, dated April 17, 1883.

Application filed November 25, 1882. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM A. ALEXAN- DER, of the city and county of Mobile, State of Alabama, have invented certain Improvements in Galvanic Batteries, of which the following is a specification.

My invention is a cheap and elfective support and connection for the elements of an electric battery and it consists in the construction and arrangement of parts hereinafter fully described, and illustrated in the accompanying drawings, in which- Figure 1 is a View showinga series of gravity-cells embodying my invention. Fig. 2 is a view showing parts detached, and Fig. 3 is a section of one of the zinc elements.

0 represents the zinc, and D the copper element, of a gravity-battery and B is the usual wood cross-bar by which the zinc element is supported in the jar A.

Instead of connecting the wire F to the zinc element by a binding-screw, I embed the Wire in the zinc at the time the latter is cast, preferably forming the wire into a loop in the body of the block, as shown in Fig. 3. This insures a most perfect and durable connection. The wire is so arranged that the ends, when extended from the sides, as shown in Fig. 1,wi11 bear upon the top of the bar B and suspend the zinctherefrom in its proper position in the fluid above the zinc. The two projecting ends of the wire permit the same zinc to be connected and included in two circuits, as is frequently required.

To avoid the loss of power resulting from the imperfect connection between the linewires and the elements, I use the coupling device E, consisting ofa short tube and a transverse binding-screw, s.

The ends of the wires to be connected are introduced into and overlapped in the tube, and then forced firmly together by means of the screw, thus not only preventing their separation, but also covering the connected ends, so as to prevent oxidation, 8w.

Without limiting myself to the precise arrangement of the wire F in the zinc, I claim- The combination, in a battery, of the jar, cross-piece B, zinc element 0, and wire cast in and extending through said element, beyond the sides thereof, constituting the hearing for the zinc upon the cross-piece, and affording connections at both sides of the cell, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

W. A. ALEXANDER.
